To all whom it may concern Be it known that I, ELMER J. Znrenna, a

citizensof-the United States of America, and

' tional View of a ;fragment f of the heater.

resident of Camden, in thecounty ofCainden and State of New Jersey, have invented certain new and useful Improvements in Water Heaters, of which the following is a specification.

This invention relates to attachments for cooking stoves, and has for an object the provision of a water heater for use in associated relation with the burners of gas stoves and the like.

It is an object of this invention to produce a top for a gas stove in which the flame may be utilized for the purpose of cooking and for the heating of water which may circulate through pipes arranged in proximity to the burner and within the zone of the heat radiating from the burner.

It is an object of this invention to produce a stove top of the character indicated which may be removably applied to gas stoves now in common use and in which the characteristics indicated are embodied, in order that the usefulness of the gas stove may be increased and water may be heated without materially increasing the cost attending the use of the stove for its initial purpose.

It is a further object of this invention to produce a stove top having a plurality of coils of pipe arranged concentric to each other, and in which provision is made for holding the coils in spaced relation to each other and against accidental movement.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this application wherein like characters denote corresponding parts in the several views, and in which Figure 1 illustrates a plan view of the removable top, showing one of the water connections Figure 2 illustrates an enlarged sectional view of the water heating top for the gas stove;

Figure 3 illustrates a sectional view of the heater with the burners in plan on a line I and Figure l illustrates an enlarged detail see- In. thesedrawings that: illustrate one em bodiment' of the invention, 5 denotesrthe casing or body of the water heating attachment having apertures 6 which are intended to register with the burners 7 of a gas stove, it being understood that the burners shall be in such position that the flame emanating therefrom will rise through the apertures into the casing.

A conventional type of stove top 8 will be employed as a cover for the casing, having apertures 9 and plates 10 for supporting 1c uklinary articles such as pans, pots and the The walls of the casing have apertures 11 constituting vents to aid in supporting combustion, and the floor or bottom of the easing has recessed ribs or flanges 12 that may be termed cradles, it being shown that the recesses 13 thereof form seats in which convolutions of the coil pipe 14 are located.

By reason of the fact that these coils of pipe are located in the seats, the said coils are held in proper spaced relation to one another and elevated from the floor of the casing in order that the flame or heat may more readily pass around the coils and affect the contents of the pipe. One end section 15 of the pipe may be connected to the source of water supply, and the other end section 16 may be connected to the water distributing system so that as the water is heated, its expansion in the coils will aid in causing it to circulate.

The bottom of the casing has an aperture 17 through which the pipe projects, and thereafter, it extends horizontally and ex teriorly of the casing, the pipe sections being preferably parallel, although the inventor does not wish to be limited with respect to this arrangement of the piping.

It has been found in practice that copper tubing or pipe is more eflicient for use in this connection than pipe made of other materials, but obviously, the inventor does not wish to limit himself with respect to the material employed in its manufacture.

The top 8 may be held in place by one or more fastenings 18 such as screws that pass through the top and may be threaded 1n the floor or bottom of the casing. When the pipes are properly placed on the cradles and then extended through the aperture in the bottom of the casing and through the aperture 19 in the side Wall respectively, the coils of pipe will retain their shape and they will not be distorted by heat from the burners.

I claim:

1. In a heating attachment for gas stoves and the like, a removable top therefor comprising a casing having apertures in its side walls and heat-admitting apertures in its bottom, cradles on the bottom of the casing having recessed upper edges forming seats, a pipe coiled to embrace the heat-admitting apertures located in the seats and having ends adapted to be connected to supply and distributing pipes, substantially as described.

2. In a Water heating attachment for stoves, a casing having heat-admitting apertures in its bottom, ribs on the said bottom having recesses in their upper edges, recessed cradles, a pipe having convolutions which are substantially concentric to the heat-admitting apertures in the bottom of the casing, said pipe being seated in the recesses of the cradles and having extensions adapted to be connected to supply anddistributing pipes respectively.
